If you're identifying color for pretty much anything digital, you're working in an RGB colorspace. If the project you're working on requires percentage representation, army green is made of 29% red, 33% green, and 13% blue.
If you're identifying color for a print project, you're most likely using a CMYK colorspace—the percentages are 10% cyan, 0% magenta, 61% yellow, 67% black.
